What is a prototype?

A prototype is a preliminary model of something. Projects that offer physical products need to show backers documentation of a working prototype. This gallery features photos, videos, and other visual documentation that will give backers a sense of what’s been accomplished so far and what’s left to do. Though the development process can vary for each project, these are the stages we typically see:

Proof of Concept

Explorations that test ideas and functionality.

Functional Prototype

Demonstrates the functionality of the final product, but looks different.

Appearance Prototype

Looks like the final product, but is not functional.

Design Prototype

Appearance and function match the final product, but is made with different manufacturing methods.

Production Prototype

Appearance, function, and manufacturing methods match the final product.

Prototype Gallery

These photos and videos provide a detailed look at this project’s development.

When testing power electronics, it is often challenging to attach oscilloscope probes to bolts and screws.   The standard probe end was designed to hook on to an 18 gage resistor lead and not much else.

We designed Probe2Bolt adapters to help make easy and more reliable test connections to bolts, studs, screws and cage type (including DIN rail type) terminal blocks.

The original prototypes were cut with punch, nibbler, shears and file.  We also had a few prototypes lasered.  We're now raising money to have parts waterjetted, nickel plated and shipped out to funders and customers.

We will also be releasing video of the hand-prototyping process with useful suggestions and tips on how to create these parts and other small sheetmetal parts at home, so that DIY'ers who may already have the tools and material can create these at home for minimal cost.

We're also interested in exploring the market and gauging interest for these parts and other potential related products and business.

Risks and challenges

Risks of this project would be:
1. Cut quality: The lasered parts we have as prototypes are beautiful. Unfortunately, they were lasered from varnished material! And lasering is expensive on copper alloy parts. We think waterjetted and tumbled parts will be good, but are awaiting taking a look at jetted samples. I am especially concerned about "loose burrs." Update 2016-2-16.. Portland Waterjet did a beautiful job with these using a vibratory deburing system. We've seen no edge quality issues and no loose burr whatsoever. The thickness after deburring tapers a bit down towards the edges which actually makes them easier to slide
2. Plating quality and price. We will be having these nickel plated. We think our plater will do these for a very reasonable "minimum lot" charge, but it may depend on factors out of our control. Update 2016-2-16.. Pioneer did a great job on the samples at very reasonable cost. We're confident in plating now.
